Installing USB adsl modem?

Hello all,
granted that I am an absolute beginner with Solaris, I'd like to use my adsl modem, t's a Zyxel prestige 630.
I managed to install and configure it under Ubuntu using the drivers from Conexant AccessRunner ADSL USB modems with Linux ; is there a chance to do the same under Solaris 10 ?

Thank you in advance,
bye
